Question

I have following model for which i want to update team which is a list:

class Users(models.Model):
    name = models.CharField(max_length = 100,unique=True)
    designation = models.CharField(max_length =100 )
    team = ListField(models.CharField(max_length =100),null=True)

I know I can first fetch the team attribute of object and the append the new value to list and then update the object with new list , but is thr any other way for updating ListField?

Answer 1

For appending a value to a list, you want to use a $push operator on the team field.
The django mongoDb engine has a hook for it:

http://django-mongodb.org/topics/atomic-updates.html

And here is the documentation on how to use the $push operator in mongodb:

Hope this helps.
